Hi Murli,
ASN.1 encoding is associated with one of the following:
-BER and versions (CER , DER)
-PER and versions(Unaligned, aligned)
-XER
-BER is fully supported by Titan; the codec functions are auto-generated , but an external function declaration in TTCNN-3 is needed to connect to them
( see refguide 4.22.4 Automatic Generation of Encoder/decoder Functions for some examples)
-For PER we need external support ,which is available with restrictions, see previous post https://www.eclipse.org/forums/index.php/t/1070344/
-Instead of the ASN.1 XER workflow, we propose a TTCN-3 based workflow, meaning that instead of converting XSD to ASN.1 plus encoding instructions, we convert to TTCN-3 plus encoding instructions.
A large category of ASN.1 protocols fall in the BER-encoded category , so for those we have direct support.
Best regards
Elemer

Hi Murli,
please check in github the SNMP protocol module https://github.com/eclipse/titan.ProtocolModules.SNMP
In /src, you have SNMPmsg_Types.asn with the definitons,
and a file SNMP_Functions.ttcn containing the codec declarations (and other stuff):
//SNMP encoder/decoder functions
external function enc_SNMPv1_Message(in SNMPv1_Message pdu) return octetstring
with { extension "prototype(convert) encode(BER:BER_ENCODE_DER)" };
external function dec_SNMPv1_Message(in octetstring stream) return SNMPv1_Message
with { extension "prototype(convert) decode(BER:BER_ACCEPT_ALL)" };
external function dec_SNMPv1_Message_backtrack(in octetstring stream, out SNMPv1_Message pdu) return integer
with { extension "prototype(backtrack) decode(BER:BER_ACCEPT_ALL)" };
external function enc_SNMPv2_Message(in SNMPv2_Message pdu) return octetstring
with { extension "prototype(convert) encode(BER:BER_ENCODE_DER)" };
external function dec_SNMPv2_Message(in octetstring stream) return SNMPv2_Message
with { extension "prototype(convert) decode(BER:BER_ACCEPT_ALL)" };
external function dec_SNMPv2_Message_backtrack(in octetstring stream, out SNMPv2_Message pdu) return integer
with { extension "prototype(backtrack) decode(BER:BER_ACCEPT_ALL)" };
external function enc_SNMPv3_Message(in SNMPv3_Message pdu) return octetstring
with { extension "prototype(convert) encode(BER:BER_ENCODE_DER)" };
external function dec_SNMPv3_Message(in octetstring stream) return SNMPv3_Message
with { extension "prototype(convert) decode(BER:BER_ACCEPT_ALL)" };
external function dec_SNMPv3_Message_backtrack(in octetstring stream, out SNMPv3_Message pdu) return integer
with { extension "prototype(backtrack) decode(BER:BER_ACCEPT_ALL)" };
I hope this helps

Hi Murli,
the first thing I have done is to change file extensions from .asn1 to .asn
and from .ttcn3 to .ttcn.
The compiler accepts them both , but during the workflow somewhere you may get around easier with these.
Then I have generated the Makefile:
and then tried to build:
after which I have received the following error:
:
In file included from ASNExample.cc:11:
ASNExample.hh:111:21: error: myPort.hh: No such file or directory
ASNExample.cc:29: error: variable 'ASNExample::myPort ASNExample::mtcType_component_mtcPort' has initializer but incomplete type
ASNExample.cc:32: error: variable 'ASNExample::myPort ASNExample::systemType_component_systemPort' has initializer but incomplete type
make: *** [ASNExample.o] Error 1
The meaning of this error is that in ASNExample.ttcn there is a port declaration
type port myPort message {
inout Message;
}
and the compiler cannot find the corresponding external C++ code.
If I change this to
type port myPort message {
inout Message;
} with { extension "internal"}
then the compiler will believe this port is internal and will not look for the external code, so everything will compile.
Of course, eventually, you will have to add some port to communicate with teh external wolrd, and then you will have to remove this extension.
I have added the code that compiles.
Best regards
Elemer

Hi Elemer,
Thanks for the tips. I'll keep these in mind.
Using titan compiler's -t option I generated the port files (cc and hh files) which the compiler is asking for. Please find the files attached.
This code compiles and generates the executable. But the problem is that the encoding is failing. I came to know this by putting print statements in the generated encoder function in the generated C++ files.
Thanks

Hi Murli,
-the compiler generates only a skeleton for the ports; these are compileable, but to be useful, they need to be completed with code ( see refguide and apiguide)
- to test the codecs, you have to do the following:
-write a template you want to encode t_DL_CCH_Message_template
-encode the value of the template with the encoding function
encode_DL_DCCH_Message(valueof(t_DL_CCH_Message_template))
the resulting octetstring should be decode-able with the decoding pair decode_DL_DCCH_Message
Try to use the codecs from TTCN and not from the test port ; in the beginning this will give you more transparency. Later , if you prefer, you can move them in the test port code.

Hi Murli,
I have modified a little your code:
In Templates.ttcn I have added the optional fields that should not be missed:
template (value) DL_DCCH_Message receiveDcchMsg := {
integrityCheckInfo:=omit,
message_ := {
counterCheck := {
r3 := {
counterCheck_r3 := {
rrc_TransactionIdentifier := 1,
rb_COUNT_C_MSB_InformationList := {
{
rb_Identity := 5,
count_C_MSB_UL := 50,
count_C_MSB_DL := 55
}
}
},
laterNonCriticalExtensions:=omit
}
}
}
};
In ASNExample.ttcn :
control {
// execute(nomatch_AcceptTC());
log(encode_DL_DCCH_Message(valueof(receiveDcchMsg)))
}
if I compile and run it , I can see the result of the encoding in the log:
13:44:17.424555 ASNExample.ttcn:116 Execution of control part in module ASNExample started.
13:44:17.424623 ASNExample.ttcn:120 '3018A116A414A012A010800101A10B3009800105810132820137'O
13:44:17.424912 ASNExample.ttcn:120 Execution of control part in module ASNExample finished.
13:44:17.424966 - Verdict statistics: 0 none, 0 pass, 0 inconc, 0 fail, 0 error.
This is the good news;
bad news is that apparently you are trying to write an RRC protocol module, and , if I remember correctly, RRC has PER encoding; so BER encoding native to Titan is not sufficient.
Again I suggest you look into the previous post about PER-encoding
https://www.eclipse.org/forums/index.php/t/1070344/

Hi Elemer,
Thanks for helping so actively.
I could compile the TTCN Script and generate the executable.
Now I'm trying to compile a complete TTCN Script Suit. I downloaded it from
ETSI and modified to replace all calls to encvalue/decvalue for ASN Types
with specific encoder/decoder functions.
Now I'm able to generate the C++ code but getting errors when compiling them.
For some C++ files compiler is crashing with error message similar to:
'cc1plus: out of memory allocating 33619967 bytes after a total of 401539072 bytes'
And for few it is giving Undeclared Symbol error for some variables.
I'm attaching the TTCN script. Please help.
Thanks

Hi Murli,
I have added a -w to the compiler flags
# Flags for the TTCN-3 and ASN.1 compiler:
COMPILER_FLAGS = -L -w
to suppress warnings; your compilation fails because the compiler detects errors during compilation; you need to fix these errors before proceeding further. At this stage the compiler will not generate C++ files as teh code is not consistent:
:
:
:
UTRAN/Common/UTRAN34_Sysinfo_Templates.ttcn:271.17-292.5: In template for record field `cellInfo':
UTRAN/Common/UTRAN34_Sysinfo_Templates.ttcn:272.31-34: In template for record field `cellIndividualOffset':
UTRAN/Common/UTRAN34_Sysinfo_Templates.ttcn:272.31-34: error: `omit' value is not allowed in this context
Notify: Errors found in the input modules. Code will not be generated.
make: *** [compile] Error 1
Most of the errors seem to be related to the incorrect use of omit in templates; probably those fields are not optional.
Best regards
Elemer

Hi Murli,
this is only possible if your source and the one you have sent differs, or the compiler version you and I use differs.
Please do a make archive and send me the created compressed file.
Also , I see a reference to make dep: don't do make dep;
make should be sufficient
you also have some version errors: do you have several versions of the compiler? which version do you use?
Please send me the output
To avoid mixing object files compiled with different versions , a make clean should be used. make clean also helps with some weird errors, pls. try it .
Please also be aware that I have upgraded Titan in github to version 5.4.0
Packages should appear soon on the Eclipse download site , but you can build you own from source.
Best regards
Elemer

Hi Murli,
from your logfiles it appears that your cygwin environment is running out of memory:
g++ -c -DWIN32 -I/home/sameer.kumar/titan/install/include -Wall -o UTRAN_ASP_Definitions.o UTRAN_ASP_Definitions.cc
cc1plus: out of memory allocating 1048576 bytes after a total of 403177472 bytes
Makefile:137: recipe for target 'UTRAN_ASP_Definitions.o' failed
make: *** [UTRAN_ASP_Definitions.o] Error 1
You probably need to increase the Cygwin memory size , see for example
https://cygwin.com/cygwin-ug-net/setup-maxmem.html
Best regards

Hi Murli,
I have done the following:
1. I have changed the platform to Linux as I wanted to compile on Linux
# Your platform: (SOLARIS, SOLARIS8, LINUX, FREEBSD or WIN32)
PLATFORM = LINUX
2. I have added 'with {extension "internal "}' to all 'port type' declarations so Titan would not look for the port code.
(Please remember that you will need to add code for each of these test ports; Titan only generates a skeleton)
3. First I compiled on a VMWare virtual machine with 3GB of allocated memory with Titan 5.3 and indeed I have run out of memory at
the very beginning:
:
:
Notify: File `UpperTesterSystemCmds_union.cc' was generated.
Notify: 679 files were updated.
touch compile
g++ -c -DLINUX -I/home/ntaf/TTCNv3-5.3.pl0-linux64-gcc4.8-ubuntu14.04-foss/include -DTITAN_RUNTIME_2 -Wall -o SSNITZ_Testsuite.o SSNITZ_Testsuite.cc
virtual memory exhausted: Cannot allocate memory
make: *** [SSNITZ_Testsuite.o] Error 1
4. So I moved compilation to a server with 32 GB of memory and Titan 5.4.
Here it became apparent that due to some changes in Titan, a -M compiler switch is needed, so I have added that too.
( That is needed for 5.4 only, and this was the reason for the differences we have seen before)
Also , in the module UTRAN_ASN1_ASP_RAB_Templates I had to change the order of some templates:
// -----------------------------------------------------------------------------

Titan should not care about template precedence, that is, the order in which templats are defined, so this is a fault in Titan, which we will investigate , but for the moment it was easier to circumvent.
Also , in
UTRAN34_RAB_Templates_r10
I had to change this template:
template (value) UL_LogicalChannelMappings_r8 cs_UL_LogicalChannelMappings_E_DCH_flexibleSize_r8 (LogicalChannelIdentity p_LogicalChannelIdUL := tsc_UL_DTCH1,
E_DCH_MAC_d_FlowIdentity p_E_DCH_MAC_d_FlowIdentity := tsc_E_DCH_MAC_d_FlowId_DTCH1,
boolean p_IncludeInSchedulingInfo := true,
MAC_LogicalChannelPriority p_LogicalChannelPriority := 8) :=
{ /* @status APPROVED (UTRAN) */
oneLogicalChannel := {
ul_TrCH_Type := {
e_dch := {
logicalChannelIdentity := p_LogicalChannelIdUL,
e_DCH_MAC_d_FlowIdentity := p_E_DCH_MAC_d_FlowIdentity,
rlc_PDU_Size := {
flexibleSize := {
lengthIndicatorSize := size15,
// the actual values are (IE value * 8) + 16
minRLC_PDU_Size := 0, //16
largestRLC_PDU_Size := 302 //2432
}
},
includeInSchedulingInfo := p_IncludeInSchedulingInfo
}
},
mac_LogicalChannelPriority := p_LogicalChannelPriority
}
};
to the equivalent:
template (value) UL_LogicalChannelMappings_r8 cs_UL_LogicalChannelMappings_E_DCH_flexibleSize_r8 /*(LogicalChannelIdentity p_LogicalChannelIdUL := tsc_UL_DTCH1,
E_DCH_MAC_d_FlowIdentity p_E_DCH_MAC_d_FlowIdentity := tsc_E_DCH_MAC_d_FlowId_DTCH1,
boolean p_IncludeInSchedulingInfo := true,
MAC_LogicalChannelPriority p_LogicalChannelPriority := 8)*/ :=
{ /* @status APPROVED (UTRAN) */
oneLogicalChannel := {
ul_TrCH_Type := {
e_dch := {
logicalChannelIdentity := tsc_UL_DTCH1,//p_LogicalChannelIdUL,
e_DCH_MAC_d_FlowIdentity := tsc_E_DCH_MAC_d_FlowId_DTCH1,//p_E_DCH_MAC_d_FlowIdentity,
rlc_PDU_Size := {
flexibleSize := {
lengthIndicatorSize := size15,
// the actual values are (IE value * 8) + 16
minRLC_PDU_Size := 0, //16
largestRLC_PDU_Size := 302 //2432
}
},
includeInSchedulingInfo := true//p_IncludeInSchedulingInfo
}
},
mac_LogicalChannelPriority := 8//p_LogicalChannelPriority
}
};
With these modifcations, your code compiles (see attached comp0.txt). It's a long initial compilation, it takes long hours to finish.
(Of course, incremental compilations - compilations afer you change something in a file- are much faster).
Memory consumption remained below 10%, but all I can say for sure you need more that 3 GB and less than 32 GB.
The linking fails though due to the missing external functions. If you comment those out it shoudl be OK.
I general , I think there is a confusion here between memory occupation during compilation, and generated file size.
They are not directly related: reducing one does not automatically and linearly reduce the other, the relation is more complex.
So I don't think all your switches are necessarry or even helping. I will retry compilation without them as well, and let you know.
In conclusion, you need a powerful server with a lot of memory to compile this code.
Best regards
Elemer

Hi Murli,
on a multicore ,
or
will start 4, 8 etc. parallel compilation threads,
so it may speed up compilation by a factor of 4, 8 etc.
Of course , this will eat up 4, 8 etc. time more memory.
So for a concrete system, it takes a bit of an experimentation to find the right compromise.
BR

Hi Murli,
great job, congratulations!
first , a couple of general observations:
-if you look in the log, you will see a lot of uninitialized module parameters:
Module Parameters has the following parameters: { px_AccessPointName := <unbound>, px_AttachTypeTested := EPS_ATTACH_ONLY (0), px_AuthAMF := <unbound>, px_AuthK := '00000000000000010000001000000011000001000000010100000110000001110000100000001001000010100000101100001100000011010000111000001111'B, px_ETWS_DigitalSignature := <unbound>, px_EllipsoidPointWithAltitude := <unbound>, px_EmergencyCallNumber := "112", px_FDD_OperationBand := <unbound>, px_HorizontalVelocity := <unbound>, px_IMEISV_Def := <unbound>, px_IMEI_Def := <unbound>, px_IMSI_Def := '001010123456063'H, px_IP_MTU_Size := 65535, px_IPv4_Address2a_UE := <unbound>, px_IPv4_Address_HomeAgent := <unbound>, px_IPv6_Address2a_UE := <unbound>, px_IPv6_Address_HomeAgent := <unbound>, px_MFBI_UTRAN_FrequencyBand := <unbound>, px_PTMSI_Def := 'C2345678'O, px_PTMSI_SigDef := 'AB1234'O, px_PWS_CB_DataCodingScheme := <unbound>, px_PWS_CB_DataPage1 := <unbound>, px_PWS_CB_DataPage2 := <unbound>, px_PWS_CB_DataPage3 := <unbound>, ....etc.
Wherever you see <unbound>, that is a module parameter that has not been initialized.
The variables, templates etc. in the code depend on these values; if these are unbound, that the depending values will be incompletely initialized as well. Exactly the symptom that is indicated in the log:
Common/IRAT/NAS_24008Templates_IRAT.ttcn:2380: Dynamic test case error: Copying an uninitialized/unsupported record/set template.
So the first thing I would do is to assign values to these module parameters.
-if you change the value of a module parameter in the code , than you will have to recompile, which takes time. A far more elegant solution is to use an appropriate config file , where all module parameters can be listed and assigned new values, without the need to recompile.
I suggest you check the projects I have uploaded in one of the previous posts, and assemble your project config file; this will be useful , even indispensable, for other reasons as well: port parameters will be taken from the config file too.
- Also in the config file one can set the logging parameters ( see refguide for possible values); if you set DEBUG as logging parameter, you will hopefully see more information in the log regarding the exact fault
Best regards

Hi Murli,
there are two ways to execute a parallel test suite:
Method I. This requires two terminals
-enter on terminal A
mctr_cli config_file_name.cfg
this will display something like:
:
:
MC@esekilxxen1842: Unix server socket created successfully.
MC@esekilxxen1842: Listening on TCP port 7298.
then enter on the same terminal :
-then enter on terminal B:
executable_name IPaddr port
where executable_name is the name of your executable
IPaddr is the IP where teh MTC executes (localhost if on the same machine)
TCP port is the port displayed on terminal A
(alternatively, the port can be fixed in the config file:
[MAIN_CONTROLLER]
TCPPort := 7298
)
-then enter on terminal A
and execution will start etc.
Method II.
One can use the ttcn3_start script
ttcn3_start executable_name config_file_name.cfg
In both cases , the config file is read and processed by the executor. Adding it to Makefile is not sufficicient.
Best regards
Elemer

Hi Elemer,
Thanks for the help. I'll try these methods for using the config file.
For now I've hard-coded the values in TTCN Files.
1. I am getting below error for some of the module parameters:
PicsPixit/Parameters.ttcn:34.69-114: error: Octetstring value contains odd number of hexadecimal digits
PicsPixit/Parameters.ttcn:44.66-71: error: Octetstring value contains odd number of hexadecimal digits
In file Parameters.ttcn corresponding changes are as below:
modulepar O43_Type px_ETWS_DigitalSignature := '1234567012345670123456701234567012345670123'O; // @desc ETWS Digital Signature
modulepar O3_Type px_HorizontalVelocity := '777'O; // @desc Horizontal Velocity to be provided in Update UE location information (see 36.509 cl 6.12)
Build log and modified files are @FileGenErrorWithFewModuleParam.zip
2. These parameters are not used in scripts so I have commented these and build was successful.
Now unbound fields are not there. But initializtion is failing at the same point.
Log is attached @SSNITZ_Testsuite.test-desktop-hc.log
3. Regarding this initialization failure I doubt below function is cauing the problem:
template (present) MS_RadioAccessCap cr_MSRadioAccessCapSingle(template (present) SingleAccessCap p_SingleAccessCap := cr_SingleAccessCapAny) :=
{ /* @status APPROVED (IMS, IMS_IRAT, LTE_A, LTE_IRAT, POS, SSNITZ, UTRAN) */
accessTechType := complement('1111'B),
singleAccess := p_SingleAccessCap, // only present if accessTechType != 1111
addLength := omit, // only present if accessTechType = 1111
addAccess := omit,
sparebits := *
};
Can this line be the reason for failure?
Are '?' and '*' syntax supported by TITAN?
Thanks

Hi Murli,
for 1. the answer is pretty straightforward: octetstrings have to have even nr. of characters by definition:
'777'O is not a valid octetstring, while '0777'O is
for 2. , Titan does support wildcards "?' and '*' , so certainly that is not the reason for failure.
What I can suggest is to comment out the template and see what happens;
also if you upload the complete project, including external functions , I can take a look myself.
Best regards
Elemer

Hi Murli,
please bear with us, we are investigating this issue, and hopefully we will have soon a solution that we'll make available for you, but it takes some time,
not unrelated to long compilation turnover.
As soon as I'll have a result, I'll let you know.
Best regards
Elemer

Hi Elemer,
I've found the following observation which you may have already noticed. I feel this may be the cause of the dynamic error I'm getting.
For copying a template to other template, following method in file "core/Template.cc" of Titan is being called in the assignment operator of the template.
Record_Template::copy_template(const Record_Template& other_value)
In this method, the field `other_value.template_selection` is checked in a switch.
switch (other_value.template_selection) {
...
}
This method is called from assignment operators of template classes in the generated *.cc code.
In code generated for assignment of basic type (INTEGER, enum) to template the method `set_selection` is called to set the value of the field `template_selection`.
But for template to template assignment, a call to `set_selection` is not generated.
Following is the expert of the generated code which throws the dynamic error.
UTRAN__ASP__Definitions::CphyTrchConfigReq_dlconnectedTrCHList_0_template cs__CphyDlConnectedTrCH__FDD__DCH(const INTEGER& p__TransportChannelIdentity, const UTRAN__ASP__Definitions::CommonOrDedicatedTFS_template& p__CommonOrDedicatedTFS)
{
TTCN_Location current_location("Common/UTRAN/UTRAN_ASN1_ASP_Templates.ttcn", 1309, TTCN_Location::LOCATION_TEMPLATE, "cs_CphyDlConnectedTrCH_FDD_DCH");
UTRAN__ASP__Definitions::CphyTrchConfigReq_dlconnectedTrCHList_0_template ret_val;
ret_val.trchid() = p__TransportChannelIdentity;
ret_val.dl__TransportChannelType() = UTRAN__ASP__Definitions::~S__DL__TransportChannelType:dch;
ret_val.transportChannelInfo() = p__CommonOrDedicatedTFS; //This line is throwing that dynamic error we're facing.
return ret_val;
}
Thanks

Hi Murli,
thank you for your help; we have found the reason for the initialization problem and working on a solution now.
All is caused by templates referring to templates which are not defined yet; situation gets more complicated with importation, when code generation has to jump back and forth between several modules.
I hope by the end of the week we will have a tested solution which I will make available via github.
Thank you for your patience
and best regards
Elemer

Hi Murli,
I have update the source code in github; the new revision is 5.4pl1 (R 4B).
Pls. try to build a Titan from scratch for your platform.
With this the initialization is successful, see attached logfiles.
Two hints:
- in the config file remove the line:
#LogFile := "run.log"
this does not work well in multi-component mode;let Titan figure out the names of logfiles (there will be separate logfiles generated for components)
- in the Makefile add the linker flag:
# Flags for the linker:
LDFLAGS = -fuse-ld=gold
The linking will use the gold linker which is a lot faster; in incremental compilation this will matter.
Pls. let me know how it goes.
Best regards
Elemer
